Manual and Auto Modes
- Long press the "Power" button for 3 seconds - the blue (LED) indicator will be ON, the manual mode is on.
- Long press the "Power" button for 3 seconds - the blue (LED) indicator will be OFF, the auto mode is on.
- In auto mode, when the input voltage exceeds 13.3V, the circuit will be connected automatically, the voltmeter and red led indicator will also be ON. When the input voltage drops to 12.8V, the circuit will be disconnected automatically, and the voltmeter and led indicator will also be OFF.

Wires Connection Guide
Voltage Sensitive Relay VSR Smart Dual Battery Isolator Kit
- CUT-IN VOLTAGE: 13.3V; DCCUT-OUT VOLTAGE:12.8V DC.
- Voltage Sensitive Relay (VSR) allows charging of two batteries simultaneously. When the engine starts and the starting battery reaches 13.3 volts, the VSR engages, allowing both battery packs to charge simultaneously (Starting Battery Pack and Household Battery Pack).
- When the voltage drops below 12.8 volts, the VSR disconnects and separating the battery. This reduces the possibility of battery depletion, effectively protects sensitive electronic devices powered by indoor batteries, and extends their service life.

Ich bin zufrieden, auch das mal das Relais Manuel ansteuern kann ist top. Wenn die Hauptbatterie mal schwächelt, kann man diese so unterstützen

After installation, the wattage to my 2nd battery increased significantly (faster charge). Plus, a second auxiliary battery also charges efficiently at up to 128 watts. That has been a wonderful surprise. Starter battery seems unaffected (that is, charges normally). Very impressive current isolation.The package is admirably kitted with extra terminals, connectors, either isolating or through. If your additional battery is not sited within 10 feet (3M), you will need additional current gauge wire (1 wire - hot). I needed another 3M to get to the other side of my truck and back to the pickup bed. I used one of the connectors supplied in the kit between the supplied hot and my extension. Heavy duty terminals were supplied in the kit.Ensure that your aux battery to ground is good. My first attempt was faulty, causing an hour of continuity debugging to find the issue.All in all this product works well. So far (2 weeks service) I’m loving the faster charge rates to both aux batteries and no affect to my starter charge.
